End to end integration test for the each PR

[fireddd]

Currently, the SDK lacks comprehensive end-to-end integration tests that validate the complete flow across all supported scenarios. Adding such tests will help ensure that the SDK works as expected after each change and will improve overall reliability.

Proposal:

• Implement an example integration test file that covers all possible scenarios supported by the SDK.
• Configure the CI to run these integration tests automatically on every pull request.
• Any required secrets for these tests (such as API keys or tokens) can be set using environment variables or GitHub secrets, ensuring sensitive information is not exposed.

Benefits:

• Increased confidence in code changes.
• Faster detection of integration issues.
